In northeastern BC they seem to call for maybe 10 days or so...unless a col=
d
snap quiets them down for a couple days, then the calendar dates are
extended, though the total nights calling are probably not. And that's for
the frogs in any one pond....the species as a whole has about a 2-week peak
around here (some ponds start later due to elevation, etc) but the earliest
and latest calling I heard last year were separated by almost a month.
I don't know what the deal is regarding the deeper and higher voiced frogs.
I've noticed the same around here, but overall, our local wood frogs have
lower pitch than the ones in Rich's example.
